Capillary Lamina of Choroid[edit]
The Capillary Lamina of Choroid (also known as Choriocapillaris) is a layer of the choroid, which is one of the three layers that make up the eye. It is the innermost layer of the choroid and is primarily composed of capillaries, hence its name.
Structure[edit]
The capillary lamina of choroid is a network of small blood vessels or capillaries that provide oxygen and nutrients to the outer layers of the retina. These capillaries are larger and more permeable than those found in other parts of the body, allowing for the efficient exchange of nutrients and waste products.
Function[edit]
The primary function of the capillary lamina of choroid is to supply the photoreceptor cells in the retina with oxygen and nutrients. It also plays a role in thermoregulation, helping to dissipate heat from the light-absorbing retina, and in visual acuity, by absorbing scattered light.
Clinical significance[edit]
Changes in the capillary lamina of choroid can lead to various eye diseases. For example, a decrease in the density of capillaries can result in age-related macular degeneration, a leading cause of blindness in older adults. Other conditions, such as central serous chorioretinopathy and polypoidal choroidal vasculopathy, are also associated with abnormalities in the capillary lamina of choroid.
